I had a proton email created when it was announced & didn't use it. I found out that my mailbox decryption for that email id is not working (not sure how, I use password manager) & I haven't set a recovery email to recover my account.
I saw a HN comment earlier telling, the user had recovered their Proton mail account by answering few questions to customer service.
I attempted the same, the issue is that I used VPN to create the email id & didn't provide any personal details for the account.
They asked questions like,
-Do you remember the exact time and date when your account was created?
-When was the last time you have accessed your account?
-What is your display name?
-Do you remember to which addresses you have sent your last messages?
-Do you remember the email subjects of the last sent messages?
I tried to answer the account creation date by using the date of password creation in my password manager (the login password was working); but the support didn't seem to buy it.
They were insistent on,
-Can you please tell us if you remember from which addresses have you received your last few messages?
-Could you tell us if you have used the ProtonMail account to sign up for some other web services?
I told them, I don't remember receiving email from anyone else & I didn't sign up for any service
-There is a service that the xxxxx@protonmail.com address has been used to sign up for. Can you please tell us what that service is?
I told them again that I didn't sign up for any service using that email id.
- Can you tell us the full address below?
no-xxxxx@drxxxxx.com
Even though I could obviously guess the username of that email id. I told them that I didn't sign up with such service, that it must be a spam mail sent by some service.
They said,
- If you have not signed up for this service, the account probably belongs to someone else.
Then I typed 'no-xxxxx@drxxxxx.com' on Google Search, the instant results gave 'no-reply@dropbox.com' as the first result.
I sent them,
Hey sorry, I remembered the service. I did signed up for Dropbox & used the account for a while.
The email id you asked was,
no-reply@dropbox.com
They reset the account & I got access to it.
Edit: Had to fix the xxxxx.
